Diazotization recovery

Mallinckrodt has reported a similar process for manufacture of OMC that involves the diazotization of p-anisidine in aqueous iodide to produce p-iodoanisole which is then reacted with OA in the presence of trialkylamine (as a base) and Pd/C, without solvent, to yield OMC the process requires the recovery of iodide and the R3N with alkali hydroxide [26]. 

Diazotized dendrimers were rednced with Au(III) [297] or Pd(II) [298] to provide the corresponding Am( p) or Pd(np) core dendrimers. Palladinm-grafted dendrimer nanoparticles catalyze the redaction of C=C and C=C at room temperature. The Pd-core dendrimer was also found to be a good catalyst in Suzuki, Stille, and Hiyama coupling reactions [299] with a good recovery and recyclability in Suzuki coupling reactions.
